* Provide git_config with a callback-data parameterJohannes Schindelin2008-05-14
| | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

* | Make core.sharedRepository more genericHeikki Orsila2008-04-16
|/ | | | | | | | | | | | | | | git init --shared=0xxx, where '0xxx' is an octal number, will create a repository with file modes set to '0xxx'. Users with a safe umask value (0077) can use this option to force file modes. For example, '0640' is a group-readable but not group-writable regardless of user's umask value. Values compatible with old Git versions are written as they were before, for compatibility reasons. That is, "1" for "group" and "2" for "everybody". "git config core.sharedRepository 0xxx" is also handled. Signed-off-by: Heikki Orsila <heikki.orsila@iki.fi> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* get_pathspec(): die when an out-of-tree path is givenJunio C Hamano2008-03-07
| | | | | | | | | | | | | | | | | | | | | | An earlier commit d089ebaa (setup: sanitize absolute and funny paths) made get_pathspec() aware of absolute paths, but with a botched interface that forced the callers to count the resulting pathspecs in order to detect an error of giving a path that is outside the work tree. This fixes it, by dying inside the function. We had ls-tree test that relied on a misfeature in the original implementation of its pathspec handling. Leading slashes were silently removed from them. However we allow giving absolute pathnames (people want to cut and paste from elsewhere) that are inside work tree these days, so a pathspec that begin with slash _should_ be treated as a full path. The test is adjusted to match the updated rule for get_pathspec(). Earlier I mistook three tests given by Robin that they should succeed, but these are attempts to add path outside work tree, which should fail loudly. These tests also have been fixed.

* Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

When working inside a subdirectory, the user-supplied pathspecs are taken to be relative to the current subdirectory. Among special path components in pathspecs, we used to accept and interpret only "." ("the directory", meaning a no-op) and ".." ("up one level") at the beginning. Everything else was passed through as-is. For example, if you are in Documentation/ directory of the project, you can name Documentation/howto/maintain-git.txt as: howto/maintain-git.txt ../Documentation/howto/maitain-git.txt ../././Documentation/howto/maitain-git.txt but not as: howto/./maintain-git.txt $(pwd)/howto/maintain-git.txt This patch updates prefix_path() in several ways: - If the pathspec is not absolute, prefix (i.e. the current subdirectory relative to the root of the work tree, with terminating slash, if not empty) and the pathspec is concatenated first and used in the next step. Otherwise, that absolute pathspec is used in the next step. - Then special path components "." (no-op) and ".." (up one level) are interpreted to simplify the path. It is an error to have too many ".." to cause the intermediate result to step outside of the input to this step. - If the original pathspec was not absolute, the result from the previous step is the resulting "sanitized" pathspec. Otherwise, the result from the previous step is still absolute, and it is an error if it does not begin with the directory that corresponds to the root of the work tree. The directory is stripped away from the result and is returned. - In any case, the resulting pathspec in the array get_pathspec() returns omit the ones that caused errors. With this patch, the last two examples also behave as expected. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you have a working tree _file_ "foo", attempt to refer to a branch "foo/bar" without -- to disambiguate, like this: $ git log foo/bar tried to make sure that foo/bar cannot be naming a working tree file "foo/bar" (in which case we would say "which one do you want? A rev or a working tree file? clarify with -- please"). We run lstat("foo/bar") to check that. If it does not succeed, there is no ambiguity. That is good. But we also checked the error status for the lstat() and expected it to fail with ENOENT. In this particular case, however, it fails with ENOTDIR. That should be treated as "expected error" as well.

For example, why do you have to provide a worktree, when it is not used? As in "git status". Now it works. Another riddle was: if you can have work trees inside the git dir, why are some programs complaining that they need a work tree? IOW it is allowed to call $ git --git-dir=../ --work-tree=. bla when you really want to. In this case, you are both in the git directory and in the working tree. So, programs have to actually test for the right thing, namely if they are inside a working tree, and not if they are inside a git directory. Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was specified, unless there is a repository in the current working directory. It does now. The logic to determine if a repository is bare, or has a work tree (tertium non datur), is this: --work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true, which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR ends in /.git, which overrides the directory in which .git/ was found. In related news, a long standing bug was fixed: when in .git/bla/x.git/, which is a bare repository, git formerly assumed ../.. to be the appropriate git dir. This problem was reported by Shawn Pearce to have caused much pain, where a colleague mistakenly ran "git init" in "/" a long time ago, and bare repositories just would not work.

The work tree can be specified using the environment variable GIT_WORK_TREE and the config option core.worktree (the environment variable has precendence over the config option). Additionally there is a command line option --work-tree which sets the environment variable. setup_gdg does the following now: GIT_DIR unspecified repository in .git directory parent directory of the .git directory is used as work tree, GIT_WORK_TREE is ignored GIT_DIR unspecified repository in cwd GIT_DIR is set to cwd see the cases with GIT_DIR specified what happens next and also see the note below GIT_DIR specified GIT_WORK_TREE/core.worktree unspecified cwd is used as work tree GIT_DIR specified GIT_WORK_TREE/core.worktree specified the specified work tree is used Note on the case where GIT_DIR is unspecified and repository is in cwd: GIT_WORK_TREE is used but is_inside_git_dir is always true. I did it this way because setup_gdg might be called multiple times (e.g. when doing alias expansion) and in successive calls setup_gdg should do the same thing every time. Meaning of is_bare/is_inside_work_tree/is_inside_git_dir: (1) is_bare_repository A repository is bare if core.bare is true or core.bare is unspecified and the name suggests it is bare (directory not named .git). The bare option disables a few protective checks which are useful with a working tree. Currently this changes if a repository is bare: updates of HEAD are allowed git gc packs the refs the reflog is disabled by default (2) is_inside_work_tree True if the cwd is inside the associated working tree (if there is one), false otherwise. (3) is_inside_git_dir True if the cwd is inside the git directory, false otherwise. Before this patch is_inside_git_dir was always true for bare repositories. When setup_gdg finds a repository git_config(git_default_config) is always called. This ensure that is_bare_repository makes use of core.bare and does not guess even though core.bare is specified. inside_work_tree and inside_git_dir are set if setup_gdg finds a repository. The is_inside_work_tree and is_inside_git_dir functions will die if they are called before a successful call to setup_gdg.

* Detached HEAD (experimental)Junio C Hamano2007-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows "git checkout v1.4.3" to dissociate the HEAD of repository from any branch. After this point, "git branch" starts reporting that you are not on any branch. You can go back to an existing branch by saying "git checkout master", for example. This is still experimental. While I think it makes sense to allow commits on top of detached HEAD, it is rather dangerous unless you are careful in the current form. Next "git checkout master" will obviously lose what you have done, so we might want to require "git checkout -f" out of a detached HEAD if we find that the HEAD commit is not an ancestor of any other branches. There is no such safety valve implemented right now. On the other hand, the reason the user did not start the ad-hoc work on a new branch with "git checkout -b" was probably because the work was of a throw-away nature, so the convenience of not having that safety valve might be even better. The user, after accumulating some commits on top of a detached HEAD, can always create a new branch with "git checkout -b" not to lose useful work done while the HEAD was detached. We'll see.

* Automatically detect a bare git repository.Shawn O. Pearce2006-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | Many users find it unfriendly that they can create a bare git repository easily with `git clone --bare` but are then unable to run simple commands like `git log` once they cd into that newly created bare repository. This occurs because we do not check to see if the current working directory is a git repository. Instead of failing out with "fatal: Not a git repository" we should try to automatically detect if the current working directory is a bare repository and use that for GIT_DIR, and fail out only if that doesn't appear to be true. We test the current working directory only after we have tried searching up the directory tree. This is to retain backwards compatibility with our previous behavior on the off chance that a user has a 'refs' and 'objects' subdirectories and a 'HEAD' file that looks like a symref, all stored within a repository's associated working directory. This change also consolidates the validation logic between the case of GIT_DIR being supplied and GIT_DIR not being supplied, cleaning up the code. Signed-off-by: Shawn O.

* Move deny_non_fast_forwards handling completely into receive-pack.Shawn Pearce2006-10-30
| | | | | | | | | | | The 'receive.denynonfastforwards' option has nothing to do with the repository format version. Since receive-pack already uses git_config to initialize itself before executing any updates we can use the normal configuration strategy and isolate the receive specific variables away from the core variables.

* add receive.denyNonFastforwards config variableJohannes Schindelin2006-09-20
| | | | | | | | | | | | If receive.denyNonFastforwards is set to true, git-receive-pack will deny non fast-forwards, i.e. forced updates. Most notably, a push to a repository which has that flag set will fail. As a first user, 'git-init-db --shared' sets this flag, since in a shared setup, you are most unlikely to want forced pushes to succeed.

* setup_git_directory_gently: do not barf when GIT_DIR is given.Matthias Lederhofer2006-07-30
| | | | | | | | | Earlier we barfed when GIT_DIR environment variable points at a directory yet to be created, which made it impossible to use configuration mechanism in "git-init-db". Signed-off-by: Matthias Lederhofer <matled@gmx.net> Signed-off-by: Junio C Hamano <junkio@cox.net>
* shared repository: optionally allow reading to "others".Junio C Hamano2006-06-10
| | | | | | | | | | | | | | | | | | | | | | This enhances core.sharedrepository to have additionally specify that read and exec permissions to be given to others as well. It is useful when serving a repository via gitweb and git-daemon that runs as a user outside the project group. The configuration item can take the following values: [core] sharedrepository ; the same as "group" sharedrepository = true ; ditto sharedrepository = 1 ; ditto sharedrepository = group ; allow rwx to group sharedrepository = all ; allow rwx to group, allow rx to other sharedrepository = umask ; not shared - use umask It also extends "git init-db" to take "--shared=all" and friends from the command line.

* revision parsing: make "rev -- paths" checks stronger.Junio C Hamano2006-04-26
| | | | | | | | | | | | | | | | | If you don't have a "--" marker, then: - all of the arguments we are going to assume are pathspecs must exist in the working tree. - none of the arguments we parsed as revisions could be interpreted as a filename. so that there really isn't any possibility of confusion in case somebody does have a revision that looks like a pathname too. The former rule has been in effect; this implements the latter. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Fix filename verification when in a subdirectoryLinus Torvalds2006-04-26
| | | | | | | | | | | | | | | | | When we are in a subdirectory of a git archive, we need to take the prefix of that subdirectory into accoung when we verify filename arguments. Noted by Matthias Lederhofer This also uses the improved error reporting for all the other git commands that use the revision parsing interfaces, not just git-rev-parse. Also, it makes the error reporting for mixed filenames and argument flags clearer (you cannot put flags after the start of the pathname list).

* Introduce core.sharedrepositoryJohannes Schindelin2005-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the config variable 'core.sharedrepository' is set, the directories $GIT_DIR/objects/ $GIT_DIR/objects/?? $GIT_DIR/objects/pack $GIT_DIR/refs $GIT_DIR/refs/heads $GIT_DIR/refs/heads/tags are set group writable (and g+s, since the git group may be not the primary group of all users). Since all files are written as lock files first, and then moved to their destination, they do not have to be group writable. Indeed, if this leads to problems you found a bug. Note that -- as in my first attempt -- the config variable is set in the function which checks the repository format. If this were done in git_default_config instead, a lot of programs would need to be modified to call git_config(git_default_config) first. [jc: git variables should be in environment.c unless there is a compelling reason to do otherwise.] Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
